This study sought to explore the ideological and implementational spaces for mainstreaming multilingual pedagogies (MPs) in initial teacher education (ITE) policies curricula across European Union. The concept of linguistically sensitive teaching (LST) was used as a lens examine inclusive, equity-centred MPs ITE. A multi-sited comparative case conducted collect data nine locations. As result, g...

Thin-layer chromatography/flame ionization detection (TLC/FID) allows for the fractionation of bitumen into four fractions, namely, the saturates, the aromatics, the resins A and the resins B (SARAB). The technique is rapid and economical, but it lack reproducibility. The effect of chromarod aging on reproducibility was investigated along with that of the time between bitumen dissolution and it...

The color of 24 commercially available denture resins was determined visually with Munsell color tabs and by reflection spectrophotometry. Correlation between Munsell and spectrophotometric data was found. The resins characterized for Black patients had a higher degree of specular reflectance and were more opaque than resins for Caucasians.

Poly(4-vinylpyridine), 4VP, resins cross-linked with oligo(ethylene glycol dimethacrylates) were used for chelating resins. Sorption for some metal ions by complexation in acetate buffer (pH 3-6) was investigated mainly by using the 4VP resins cross-linked with hydrophilic tetraethylene glycol dimethacrylate (4VP-4EG) and that cross-linked with hydrophobic divinylbenzene (4VP-DVB). The differen...

The use of epoxy resins in metal structures for adhesive reasons is getting wider. Epoxy resins possess enhanced mechanical, chemical and physical properties, i.e. increased shear and compression strength, resistance in solvents, as well as at high temperatures. Tensile tests were carried out with standard aluminium tension specimens glued with epoxy resins. The thickness of the glue and the ac...

Composites resins are the most popular restorative materials providing very good esthetics and long period of good clinical performance. Depth of cure of composite resins is crucial in determining the maximal increment thickness when restoring tooth cavities. In restorations with conventional composite resins the thickness of each increment has been defined as up to 2 mm. Bulk fill composite re...
